Zusammenfassung:	The invention discloses a method and a device for constructing a tobacco shred structure prediction model. The method comprises the following steps: detecting a leaf structure of each tobacco flake sample and a shredded tobacco shred structure; principal part analysis is conducted on the leaf structure of each tobacco flake sample, a preset number of principal parts with the cumulative variance contribution rate larger than or equal to 95% are selected as target principal parts, and a score coefficient matrix of the target principal parts is output; constructing a score calculation model of each target principal part and the blade structure based on the score coefficient matrix, and performing calculation to obtain a score of each target principal part; performing stepwise multiple regression analysis on the score of each target principal part and the tobacco shred structure, and outputting a regression model of the score of the target principal part and the tobacco shred structure; and combining a score calc
